5 Claims.

The present invention relates to threshing mechanisrnand an object thereof is to. generally improve the construction and operation of machines of-this class.

A further object is to provide. improved mounting for the cylinder shaft in such a mechanism, the present application being a division of the application of Norman R. Krause, Serial No. 333,489, 'fiied May 6, 1940, now Patent No. 2,336,- 263, for Combinationharvester threshers.

Further objects and advantages will become apparent from the following specification and accompanyingdrawings in which Figure 'l is a side elevation of so muchof a thresher mechanism as necessary to illustrate the invention.

Fig. 2 is a horizontal sectional View of the same taken on the line 22 of Fig. 1.

As seen in'Fig. 1,.5 represents a wall portion of a thresher or harvester thresher which is united with and at least in part supported by a sill or longitudinal structural element generally designated as E, in the presentinstance comprising an angle iron having an upright flange 7 and a horizontal flange 8. A cylinder shaft or axle 9 is required to be substantially supported and accordingly the for mounting the same is included as part of the general framing of the thresher or combine. Shafts is carriedinbearings, only one of which is necessary to be described and generally designated as Ill, the details of the cylinder formingno part of the present invention, the shaft only being disclosed.

Upright braces or members generally designated as l l and i2, conveniently comprising angle irons having flanges l3 and M respectively, lying against wall 5 and projecting flanges l5 and I6, are suitably fixed as by welding, riveting or the like with sill 't and extend upwardly along wall 5. Flanges l5 and it extending outwardly as they do, provide a channel ll between them. A block l8 is placed in channel I! and carries a bearing generally designated as IE3 which may be of any suitable type forming no part of the present invention, block if; and bearing l9 constituting a bearing unit which may be adjusted as will appear. Jack bolts 29 and H extend through above mentioned flange 8 of sill ii and may be locked therein as by nuts 22 to 25 inclusive. Bolts 28 and 2i are preferably, although not necessarily, flattened at 26 and 2'! respectively and other bolts 28 and 29 extend through the flattened portions and through outwardly directed flanges l5 and I6 and also through block I 8, bolts 28 and 29 including heads at and 3! respectively and being arranged-for clamping flattened portions 26 and 21, flanges L5 and-i Hi and block l 8 rigidly together as by means of nuts 32 and 33 which in turn may be secured as-by locknuts 34.and 35-respectiveIy. In thislmannerblock I 8 andibearing 19. arecarried man.,extremelysstable and substantially rigid mannersdirectlyifrom sills.

It isdesirableto locate cylinder shaft 9 quite accurately ,withz-relation to'internal parts of the threshing =mechanism, .not shown, and forming no ,part'of the present invention. Slots as 36 areathereforeiformed infianges 1:5 and l6ior the accommodaticnof bolts 28 and-.29 whereas said boltsare relatively. closely fitted in fiattenedportions izfiiand Z'Lof .jackbolts 20 and 2| and also iniblock .i;8. Byiadjusting nuts 22 and 24 while clampingnutsiiizcand :33, and also nuts 23 and 25. are, loosenedblcck l 8.may accordingly be very accurately raisedorlowered in channel 11 to obtain the desired adjustment of shaft 9. If block 88 resists down-ward movement, it may be readily forced by tightening nuts '23 and 25. When tench-adjustment is-secured,:nuts 32 and 33 may be tightened"andalsoisuchaof nuts '22 ,to Ziaszare leose-ratzthe'moment, whereuponfianges I 5 .;and t6 :and b'olts .120 :and 2| will be rigidly clampedttogetherand'the block and bearing very stronglysupported 'by braces ll and'l2 and bolts 29 and ZI. Bolts 2-0 and 2| therefore act as adjusting meansas wellasanchoring means for blockl=8 and-bearing 19.

To facilitate the above outlined adjustment, it is desirable but not imperative that hearing unit is be of a type permitting substantial misalignment, many of which are well-known.

The operation of the invention is thought to be clear from the foregoing description which sets forth an illustrative embodiment of the invention and what is claimed as new and desired to be secured by Letters Patent of the United States is:

1. In a. thresher, a housing having a longitudinal structure element, a shaft for supporting a threshing cylinder in said housing and a bearing supporting the shaft, spaced upright members carried by said longitudinal structural element, said bearing being carried between said upright members, slots in said upright members and a bore in said bearing aligned with said slots, jack bolts extending in the general direction of said spaced members and having bores aligned with the bore in said bearing, a bolt traversing said aligned bores and slots and arranged for clamping said jack bolts, said upright members and said bearing in rigid relation, and means for adjustably anchoring said jack bolts to said longitudinal structural element.

2. In a thresher, a housing having a longitudinal structural element, and adapted to carry a threshing cylinder therein, a shaft for supporting a threshing cylinder and a bearing unit supporting the shaft, a substantially vertically extending brace connected with said longitudinal structural element and having a projecting flange, said bearing unit providing Vertically spaced bores and said flange providing vertically spaced slots, clamping bolts in said bores and projecting through said slots, 2, jack bolt disposed on the opposite side of said flange from said bearing unit engaged with said longitudinal structural element and having vertically spaced bores aligned with the bores in said bearing unit, said clamping bolts being engaged in said vertically spaced bores, and means for adjustably anchoring said jack bolt to said longitudinal structural element for supporting said bearing and adjusting it in position relatively to said longitudinal structural element.

3. In a thresher, a housing having a longitudinal structural element and adapted to carry a threshing cylinder therein, a shaft for'supporting a threshing cylinder and a bearing unit supporting the shaft, spaced upright members carried by one of said longitudinal structural elements, said bearing being carried between said upright members, slots in said upright members and bores in said bearing aligned with the slots, jack bolts engaged with said longitudinal structural element extending in the general direction of said spaced members and having bores aligned with the bores in said bearing unit, bolts traversing said aligned bores and slots and arranged for clamping said jack bolts, said upright members and said bearing unit in rigid relation, and means for adjustably anchoring said jack bolts to said longitudinal structural element.
